Sealing systems

The all-rounders based on polyurethane and silicone

Reliable and efficient protection

The basic task of sealing systems is to efficiently protect components against moisture, chemicals, and various environmental influences.

RAMPF Polymer Solutions is a leading specialist in liquid to highly thixotropic two-component foam gaskets and elastomer seals based on polyurethane and silicone.

The foam gaskets are processed using FIPFG (formed in place foam gasket) or FIPG (formed in place gasket) technology.

Unlike dispensing system gaskets that are inserted or stuck on, the foam gaskets are applied directly to the component. They expand in situ and bond very quickly, which reduces cycle times and also ensures more efficient processing.

 

Our RAKU® PUR and RAKU® SIL systems combine efficient sealing with the highest quality and exceptionally easy handling.

By developing new products and optimizing existing ones, RAMPF ensures the toughest demands in terms of seal quality, sealing geometries, and mechanical, thermal, and chemical resilience are always met.

What’s more, processing properties such as reactivity, viscosity, and color can be tailored to customer requirements.

 

Your key benefits

Our solutions for your applications

The performance requirements of a sealing foam vary depending on the industry, product application and production process. The acquirement of the sealing systems from RAMPF Polymer Solutions offer the optimum solution for a large number of components in a wide variety of industries.

eMobility

Electromobility – one of the biggest trends. The future cars will drive electrical, noiseless and with low emissions. The essential component of an electric car is the electric motor with its battery. To ensure the performance of the battery, it´s indispensable to envoid it of external influences like dust and moisture. Due to their strong performance, the sealing foams from RAMPF are able to meet even the toughest challenges.

Control cabinet industry

In the control cabinet industry, the compensation of tolerances plays an important role in addition to the optimum protection of the component. Whether indoor or outdoor applications: RAMPF has the right sealing foam for every area in its portfolio. These are characterised by high sealing quality (confirmed by IP tests), resistance to ageing, low assembly forces and optimum adhesion to various housings such as stainless steel, aluminium, powder coating, glass and plastic. RAMPF sealing foams are UL-certified.

Appliance industry

High volumes, fully automated production processes, extremely fast cycle times, low costs and the highest quality: The appliance industry (white goods) is a global business with a strong competition. With high-performance, integrated sealing solutions, we ensure that your products are always at the forefront. Sealing systems from RAMPF make a decisive contribution to functionality and safety and thus to the satisfaction of the end customer. Since liquids are used every day in white goods, a reliable seal is all the more important. With RAKU® PUR sealing foams RAMPF guarantees long-term tightness and functionality of numerous appliances.

Automotive

Well-known car manufactures already use the sealing systems from RAMPF Polymer Solutions. This is because the sealing foams meet the demanding requirements of the automotive industry, for example the emission regulations in conjunction with extremely short cycle times. The main benefit is the fast curing of the sealing foam RAKU® PUR Speed which can be further processed after three minutes. The sealing foams from RAMPF are used in a lot of different automotive applications, such as door modules, loudspeaker boxes, fuse boxes, battery covers as well as brake and rear lights.

Packaging

The demands placed on packaging and the sealing systems used are increasing. Whether for the food industry, technical or chemical materials: RAMPF sealing foams guarantee an optimal result. RAKU® PUR sealing systems offer perfect protection against contamination and guarantee the safe transport and storage of goods, chemicals and groceries. The sealing solutions are used in steel and plastic drums with lids, steel cans and IBCs.
